[Solved/Workaround] Kernel panic with archck

isofluran · 2006-03-02 22:09:37

I have a new archlinux installation on an ibm t40p laptop. As done on two other (desktop) systems I like to switch to archck to get the 1400x1050 frambuffer running.
With pacman I installed the archck kernel and build the initramfs file with the "mkinitramfs full kernel_version=2.6.16-archck" command (I also tried the auto option but it makes no difference.)

Booting the archck kernel with grub always ends with this message:

mount: Mounting /dev/root on /new_root failed: No such device or address
umount: /initrd: No such file or directory
umount: /initrd: No such file or directory
chroot: cannot execute /bin/sh: No such file or directory
Kernel panic - not syncing: Attempted to kill init!

I hopefully found this thread (http://bbs.archlinux.org/viewtopic.php?t=18782)
but it does not solve my problem, because the menu.1st is edited correctly AFAIK.

The menu.1st section for the standard and the archck kernel:

# (0)
title Archlinux
root (hd0,4)
kernel /vmlinuz26 root=/dev/hda7 vga=795 ro
initrd /initrd26.img

# (1)
title ArchlinuxCK
root (hd0,4)
kernel /vmlinuz26archck root=/dev/hda7 video=vesafb:ywrap,mtrr,1400x1050-32@50 ro
initrd /initramfs-2.6.15-archck.img

BTW the standard kernel is booting without any errors.

Any ideas?

This probably isn't the solution, but you should use "full" OR "kernel_version=etc" - not both.

isofluran · 2006-03-03 05:48:47

This isn't really a solution.
None of the different initramfs files work. I tried the full, auto and kernel_version options in all possible combinations (and I changed the initrd line from initramfs-2.6.15-archck.img to initramfs-full.img).

Still waiting for any hints ...

isofluran · 2006-03-03 08:22:00

There is maybe a problem mounting the root partition because of its filesystem: The root partition is xfs. Is it possible that there is a problem with the xfs module?
I'm not firm with these things because I never had any problems with the kernel of archlinux (neither standard nor archck), so this is a new experience to me.

iphitus · 2006-03-03 08:43:50

what versions of archck and mkinitramfs do you have, check in pacman.

iphitus

isofluran · 2006-03-03 10:06:44

mkinitramfs 1.2-2
kernel26archck 2.6.15.archck4-2

isofluran · 2006-03-04 08:55:22

I did a complete new installation first with the same fs (xfs) and this gives me the same kernel panic. Now I changed the root partition to ext3 and all is fine. Maybe it is really a problem related to the xfs module.
So this is not a true solution but a good workaround for me.

STiAT · 2006-03-20 03:01:52

Can confirm a problem like this exists.
I freshly updated my system ... now i'm stuck with this kernel panic...

Failed to execute /init
Kernel panic - not syncing: No init found. Try passing init= option to kernel.

iphitus · 2006-03-22 01:46:28

Are you passing any init= options at the bootloader? remove them if you are.

iphitus

STiAT · 2006-03-22 16:13:31

No, i'm not.

My bootloader lines (grub)

root (hd0,6)
kernel /vmlinuz26archck root=/dev/hda9 video=vesafb:ywrap,mtrr,1024x768-32@60 splash=verbose,theme:darch ro
initrd /initramfs-2.6.15-archck.img

Since i didn't know if you also meant the initrd line, i removed the initrd line for a small test, but as expected:

VFS: Cannot open root device "hda9" or unknown-block(0,0)
Please append a correct "root=" bootoption
Kernel panic - not syncing: VFS: Unable to mount root fs on uknown-block(0,0)

Hey, I've got exactly the same problem! Did you find any solution yet?

STiAT · 2006-03-23 10:06:14

No, i didn't find any solution yet.

Still playin' around.

gunnix · 2006-03-23 10:31:59

Yea me too.. I've tried some stuff but nothing worked.

iphitus · 2006-03-23 10:49:33

what sort of setup do you guys have?

what filesystem is your / fs on?
can I get some context, something like the whole 10 lines before the error?

iphitus

gunnix · 2006-03-23 11:15:39

Sure!

I have 2 partitions (+1 swap)
/dev/hdb1 which is /boot --> ext2
and /dev/hdb3 which is / --> ext3

lines before including error:

Suspend2 Core.
Suspend2 Compression Driver loading.
Suspend2 Encryption Driver loading.
Suspend2 Swap Writer loading.
Suspend2 FileWriter loading.
ACPI wakeup devices:
PCI0 USB0 USB1 USB2 USB6 USB7 USB8 USB9 LAN0 MC97 UAR1 ECP1

Freeing unused kernel memory: 196k freed
Failed to execute /init
Kernel panic - not syncing: No init found. Try passing init= option to kernel.

The vesa framebuffer starts at boot now, but before I upgraded I never had the framebuffer starting.

iphitus · 2006-03-23 11:25:45

That sheds some more light

Could I get your /etc/mkinitramfs.conf and any commands you used to generate your initramfs?

iphitus

gunnix · 2006-03-23 15:15:27

Well I did try

mkinitramfs auto
mkinitramfs full

I did adjust menu.lst correctly.

This are the versions I have installed, I run arch from current and extra repositories:
kernel26archck 2.6.15.archck7-4
mkinitramfs 1.3-5

My /etc/mkinitramfs.conf (I did not edit anything there actually):

Now I have another error message, but it panics about on the same point where it can't find the root filesystem.

I'm going to try to add ext3 manually.
I was mistaken about my filesystem before, this is my fstab:
----------
/dev/hdb3 / ext3 defaults 0 1
/dev/hdb1 /boot ext2 defaults 0 1
/dev/hdb2 swap swap defaults 0 0

/dev/hda1 /mnt/hda1 ext3 defaults 0 1
-------------

Well thanks for reading this.

I ordered a new cdr drive to be able to get a working console. Since it's a notebook it's not that easy....

Should be about a week till i can give you proper information about this.
As i remember i have a matching setup
a /boot partition (ext2 or ext3, dont remember ... the system was updated since 0.7 ... so a quite long time ago since i did the setup on that machine )
a /root partition, reiserfs
a /home partition, reiserfs

Since i changed job recently it's not a problem to do a new setup. But i'd prefer to get it running without setting up the whole machine again....

I think since gunnix has exactly the same problem it may also is the same solution in the end.

To add some more info, this is my menu.lst:

# (0) Arch Linux
title Arch Linux hdb3 [/boot/vmlinuz26archck]
root (hd1,0)
kernel /vmlinuz26archck root=/dev/hdb3 ro
initrd /initramfs-2.6.15-archck.img

# (0) Arch Linux
title Arch Linux hdb3 [/boot/vmlinuz26]
root (hd1,0)
kernel /vmlinuz26 root=/dev/hdb3 ro
initrd /initrd26.img

# (0) Arch Linux
title Arch Linux hdb3 [/boot/vmlinuz26archck]
root (hd1,0)
kernel /vmlinuz26archck root=/dev/hdb3 ro
initrd /initramfs-full.img

I usually used the upper one, the others I added to try getting the system to boot but those won't work either. I always get a problem where it can't find root.

Hi,

just wanted to test the beyond and archck kernel. I have similar problems. But what to do exactly ?
